Jody didn’t want Mill-wheel with him for two reasons. What were they?

Jody took the help from Mill – Wheel to find the fawn. But on the way, Jody realized that he did not want him to be with him to find the fawn. There were two strong reasons to not take Mill with him. Firstly, he thought if the fawn was found dead or could not be found, then he did not want to expose his disappointment in front of Mill. Secondly, if Jody finds the fawn, he didn’t want Mill-Wheel to see his emotions and love for the fawn.
